CAS 25322-68-3
:Polyethylene glycol
Description:
Polyethylene glycol (PEG), with the CAS number 25322-68-3, is a versatile polymer known for its hydrophilic properties and biocompatibility. It is composed of repeating units of ethylene oxide, resulting in a structure that can vary in molecular weight, which influences its physical and chemical characteristics. PEG is typically a colorless, odorless, and viscous liquid or a waxy solid, depending on its molecular weight. It is soluble in water and many organic solvents, making it useful in a wide range of applications, including pharmaceuticals, cosmetics, and food products. PEG serves as a lubricant, humectant, and emulsifier, and is often used in drug formulations to enhance solubility and bioavailability. Additionally, its non-toxic nature and ability to form hydrogels make it valuable in biomedical applications, such as drug delivery systems and tissue engineering. However, the specific properties of PEG can vary significantly with its molecular weight and formulation, which must be considered when selecting it for particular applications.

CAS:<p>Bis-dPEG®5, Half Benzyl Half NHS Ester is a heterobifunctional cross-linking reagent, which is derived from discrete poly(ethylene glycol) chemistry. It features a benzyl group on one end and an N-hydroxysuccinimide (NHS) ester on the other. The NHS ester is a well-known active ester that facilitates the formation of stable amide bonds with primary amines, commonly found on proteins and peptides. By doing so, it enables the covalent attachment of biomolecules, enhancing solubility, stability, and overall bioavailability.</p>Formula:C24H50O13Purity:Min. 95%Molecular weight:546.65 g/molPoly(ethylene oxide) - average Mv 200,000
CAS:Controlled Product<p>Polyethylene oxide is a linear polymer with an average molecular weight of 200,000. It has a viscosity of approximately 8,000-10,000 cps and is soluble in water. Polyethylene oxide can be used as an excipient for pharmaceutical products. This material is not toxic or carcinogenic and does not cause hypersensitivity reactions. It is metabolized by the liver and excreted in the bile. The polyethylene oxide molecule contains hydrophilic ethylene oxide (EO) and hydrophobic oxyethylene (OE) groups that are responsible for its solubility in water and its low toxicity. The EO groups are responsible for the high viscosity of polyethylene oxide, while the OE groups contribute to its low toxicity.</p>Formula:(C2H4O)n•H2OPurity:Min. 95%PEG 3350 - Average Mw approx 3350
